Abstract: Hand hygiene is one of the most important measures available to prevent infectious diseases such as COVID-19, and it is recommended that individuals wash their hands periodically before and after meals, after using toilets, before preparing food at home, at schools, and in public places. The aim of this study was to investigate the relationship between oral hygiene and hand hygiene in Korean adolescents. Data from 57,303 adolescents who participated in the 2019 Korea Youth Risk Behavior web-based survey were analyzed to determine the relationship between oral hygiene and hand hygiene. A complex sample logistic regression analysis was performed to determine association between toothbrushing behavior and handwashing practices. According to the results of this study, adolescents who brushed their teeth after lunch were 1.48 times more likely to practice handwashing before lunch than were those who did not brush their teeth after lunch ( p < 0.001). In addition, the odds ratios adjusted for gender, grade, school type, and residence were found to be 1.87 ( p < 0.001). Moreover, these adjusted odds ratios were higher in students who received personal hygiene education (OR: 1.98, p < 0.001). Oral hygiene practices were found to be related to personal hygiene, as assessed by handwashing, in Korean adolescents. Additional studies are needed to develop ways of improving the hygiene and health of adolescents.
